Abstract :
The Hk distribution was measured in many different commercial samples of particulate and thin-film media. In all cases, relatively large Hk distributions which do not seem to correlate with the remanence switching field distribution (or coercive squareness) values or with the media noise. This leads to the conclusion that switching field distributions in oriented media do not derive from or relate to the anisotropy field distributions in these media. No media with small anisotropy field distributions were found
